Just tried to move the Coach after a day of minor cleanup. Turned the Ign key and did not even get a click. Tried the Boost and got the same thing, nothing. Batteries are fully charged, Onan cranks up just fine.
Used a jumper across the Neutral switch, still nothing.
When I turn the key to ACC, the door and gen lights come on, along with the Buzzer, when I go to start, the lights stay on but the buzzer stops.
Suggestions appreciated.

Check all battert cables, and connections first, but I'm gonna suspect the ignition switch on this one. Use a dmm and test the switch for openess...

In ACC. the air compressor comes on, turn on Headlights, turned to Start, lights did not dim, compressor kept running. I hear a very very light click, not from the Solenoid.
I have already jumped the two purple wires on the Neutral switch.
Going to leave it till morning now, the Mosquitoes are really bad once the Sun goes down.
Real happy it happened in the driveway.
Thanks for the ideas, will post tomorrow.

Richard, I would suspect the neutral/park safety interlock switch. They
sometimes loosen up and come out of adjustment. The lights and accessories
all work, but the starter solenoid does not pull in. No click, no nothing. A
quick simple test to verify battery condition is to turn on head lights have
someone watch while you attempt to start it. If the lights dim almost to
extinguish when you turn the key, it is a good sign that your batteries are
discharged or cables are at fault. It also might be a faulty starter
solenoid, but you should hear a distinct click when the key is turned to the
start position. Finally, check the column switch near the base of the dash.
Hope this helps.

Richard,
Once you've checked the fuses turn on the ignition and if you can turn the
steering wheel without the engine running into a hard right turn then turn
the ignition off. Make sure the trans is in Park, chock the wheels, crawl
under the passenger side. Put on a pair of gloves and using a heavy jumper
wire jump the small terminal on the solenoid to the large cable from the
battery. The solenoid should engage and the engine turn over. It won't start
as the ignition is off.
If you are concerned crawling under the GMC then remove the passenger side
wheel well to gain access to the starter.
If the engine turns over the problem is in the wiring from the steering
column or the ignition switch.
Regards,
Rob M.

I just had a similar problem and it turned out that the wire to the starter solenoid was shorted to ground probably touching the exhaust manifold. Just moved the wire and it started - not before I swapped the solenoid while parked at the pump in a gas station though.

Richard: Howard Nylander had the same symptmons? His was the ignition switch was out of adjustment just barley enough not to start. I figure the rod or the ignition switch wore after 30 years. The switch is accesable from the floor board. If you reach under the left side of the column you can feel a small bolt at the top and bottom of the switch. If you loosen these the switch will slide up and down. If you leave the ignition locked IIFC slide the switch up a small amount but not enough to click and tighten down. Just be sure to check if the accessory and start will work. I hope this isn`t to confusing and it helps.
See you at the Blue Angels Rally??

Could be starter switch on steering column. Happened to me once. Chuck Boyd
fixed it. He removed the switch and sprinkled a little graphite to make it move
a little smoother, adjusted switch to where rod from key would activate the
switch. Works great now. Glad it happened in my driveway too.

I have 12.8V on both sides of the purple wires which I have jumped. All of the Fuses behind the Glove Box are good and have 12.8V with the key on. The lights do not dim when I try to start.
The Buzzer and A/C Blower work
I am unable to get under the Coach to check the Starter connections and attempt to energize the starter.
I have 12.79V on both sides of the Boost Solenoid. (at least that is what I think that solenoid is.)
Questions
Looking at the wiring diagrams I cannot find the Purple wire and were it goes.
What are the other wires and switch (same place as the neutral switch) attached to the steering column?

The lowermost switch on the column is the neutral safety switch/back up lights switch (adjusts r to l. The switch above it is the ignition switch (adjusts up and down).
I believe you can get to the starter wires from inside the coach under the hatch..

Not sure if this could be the problem, have a brown nbr 10/12 wire that comes out of the wire loom on the passenger side of the Engine, about half way back, it travels back along the Intake Manifold, down behind the engine then back towards the front of the engine. It is completely loose, there is evidence of recent attachment and the eye connector would fit something 1/4 inch or less.
I was able to get far enuf under the front of the Coach so I could see a portion of the Starter Solenoid, there is the 12V from the Battery attached but no other wire that I can see on the small terminal just to the inside of the large 12v terminal.
This wire shows 12.98V when I turn to start.
I hesitate trying to attach this wire without asking here for advise.
